Okenia rhinorma Rudman, 2007
Click the thumbnail photos to enhance!
Okenia rhinorma is elongate and relatively high with a distinct ridge running around the mantle edge.
The rhinophores are extremely long. The body is opaque white with a pattern of translucent regions, and orange
and purple patches or spots. The size and proportion of orange and purple patching varies in different animals.
The lateral papillae are white with orange tips and a subapical purple band. The rhinophores are translucent white
mottled with purple patches, orange at the tip.
Let me quote Bill Rudman concerning its name: "I made the species name up by combining
rhin from 'rhinophore' and orma from 'enormous' because of its unusually long rhinophores."
